SAN RAMON, California –Chevron is planning to decommission several installations offshore Australia following production declines at the Saladin, Cowle, Yammaderry, Crest, Roller, and Skate fields.

Beyond the onshore production plant,decommissioning should include platforms at Saladin and shallow-water monopods at Roller, Skate, Yammaderry, and Cowle. Subsea flowlines from the fields to the onshore installation are included in the decommissioning plans.

The company plans to use a jackup and construction vessel with a crane for the offshore work and a workover rig for the task of plugging the wells.

It is anticipated the work will begin in 2016 and take about 12 months to complete the offshore work.

Santos Ltd. and ExxonMobil Corp. are partners with Chevron in the developments. Efforts to sell the production systems were unsuccessful, leading to the decommissioning plans.
